-: In this section, we're going to discuss perimeter security.
Now, when we talk about perimeter security,
we're focused on the outer layer
of our defense-in-depth posture for our networks.
This is the boundary
where we segment our LAN from the WAN
and from the Internet at large.
When we focus on the boundary, or perimeter defenses,
we utilize many different devices.
In this section, you're going to learn all about firewalls,
proxy servers, honey pots and honey nets,
data loss prevention systems,
network intrusion detection systems
and network intrusion prevention systems,
and combination devices,
like a unified threat management system, or UTM.
A lot of this is going to be a review
from your Network+ studies,
so we're going to cover this section fairly quickly,
pointing out the things you need to know
for the Security+ exam.
So, let's get started with our exploration
of perimeter security devices.
